Mixing functional and object-oriented programming in JavaScript

Object-oriented programming has been the dominant programming paradigm for several decades. It is taught in Computer Science 101 classes around the world, while functional programming is not. It is what software architects use to design applications, while functional programming is not. And it makes sense too: OOP makes it easy to conceptualize abstract ideas. It makes it easier to write code.

So, unless you can convince your boss that the application needs to be all functional, we're going to be using functional programming in an object-oriented world. This section will explore ways to do this.
